Well, but CONFIG_X86_ELAN=y always worked/booted fine on generic hardware - including later AMD CPUs. I have booted it on an AMD Athlon64 CPU today: config-Wed_May__4_09_26_50_CEST_2011.good:CONFIG_X86_32_SMP=y config-Wed_May__4_09_26_50_CEST_2011.good:CONFIG_MELAN=y config-Wed_May__4_09_26_50_CEST_2011.good:CONFIG_SMP=y When it comes to regressions it's past behavior that counts, not the Kconfig help text.
